Thanks for your help and interest with my masking issue. Unfortunately resetting prefs didn't fix the issue. I found my old Lightroom 4 and it was working correctly however since it cannot open current catalogs its but much help.

If you have any other suggestions That might help please let me know, this is one if those pull your hair out problems in have to resort to masking in PS then reimporting to LR. Btw I am on Mac running Yosemite OS X 10.5.5

After upgrading to LR 6.3 the making issues mysteriously disappeared. When I first upgraded problem was still present, however after using LR 6.3 for a short time masking issues were gone. This is weird but a good thing, so after 3-4 days of using it the issues have not returned and somehow the problem solved itself. Thank you for your help on these issues. all the best. Happy holidays. -dC
